Abstract:
Mycotic aneurysms resulting from intravesical bacillus Calmette-Guérin (BCG) treatment are exceptionally rare. We report on the case of a 73-year-old man who underwent intravesical therapy of BCG for bladder carcinoma and developed a right neck mass. A carotid pseudoaneurysm within a fibrotic mass was noted on surgical exploration. Radical resection was performed followed by a polytetrafluoroethylene interposition graft. Final pathology revealed necrotizing granulomas and multinucleated giant cells concerning for tuberculoma. Intravesicular BCG immunotherapy is an accepted treatment for patients with urothelial carcinoma. Carotid aneurysms are exceptionally rare in this setting and should prompt evaluation for systemic tuberculoid dissemination.
